The Breakdown and Self‐Clearing Performance During the Energy Harvesting Process of Dielectric Elastomer Generators Using Single‐Walled Carbon Nanotubes Electrodes

High Voltage, EarlyView.
ABSTRACT For dielectric elastomer generators (DEG), electrical breakdown is the main failure mode during their working cycle. The application of self‐clearing electrodes is of great significance to avoid a single breakdown leading to the failure of the entire generator.

Polyamide Acid–Based Surface Modification of Poly(p‐Phenylene Benzobisoxazole) Fibres Reinforcing Syntactic Foam for Using Them as High‐Performance Insulating Core Material

High Voltage, EarlyView.
ABSTRACT The insulating core is an important part of pillar composite insulators used in power transmission systems. Traditional insulating core materials suffer from various problems that can threaten the reliability of insulated equipment. Syntactic foam (SF) exhibits excellent properties, such as a low density, water penetration resistance and high ...

Dynamic Bayesian Network for Continuous Health Index Estimation and Condition Assessment of Power Transformers

High Voltage, EarlyView.
ABSTRACT To address the limitations of traditional transformer health index (HI), such as high dependence on data integrity and inability to assist in diagnosing latent faults, this study proposes an HI prediction method based on dynamic Bayesian network (DBN).

Dielectric Breakdown Characteristics of Biaxially Oriented Polypropylene Films: Surface Structures on Thickness Dependence

High Voltage, EarlyView.
ABSTRACT Film capacitors, essential for energy storage in power systems, benefit from reduced film thickness to increase capacitance and lower costs. While the inverse power law traditionally links higher electric strength with thinner films, its validity diminishes below a critical thickness.

Divergent shifts in hydraulic versus carbon acquisition functional traits after wildfire in four Rocky Mountain tree species

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change has increased the frequency and severity of drought and large wildfire events across western North America. Despite the increasing concurrence of drought and wildfire events and the importance of forests as a global carbon sink, the impacts of fire on ...

Online real estate agencies and their impact on the housing market

Real Estate Economics, EarlyView.
Abstract Online platforms have transformed many markets, as evidenced by the rise of firms such as Amazon, Uber, and Airbnb. However, the recent emergence of online real estate agencies has not yet received much attention. We investigate the impact of online agencies on the housing market.

denim: An R package for deterministic compartmental models with flexible dwell‐time distributions

Methods in Ecology and Evolution, EarlyView.
Abstract Compartmental models are widely used for dynamical systems where states are discrete, such as in infectious disease epidemiology with the so‐called Susceptible‐Infectious‐Recovered (SIR) framework. For mathematical simplicity, rates of transition between compartments are generally assumed to be independent of the dwell time (or secondary ...

The public agglomeration effect: Urban–rural divisions in government efficiency and political preferences

American Journal of Political Science, EarlyView.
Abstract Why and when do cities vote for the left? The emergence of the urban–rural divide in the United States in the 1930s is inconsistent with canonical theories of cleavages. This paper introduces an explanation: agglomeration effects. The provision of government services is more efficient in urban environments because of nonrivalries, economies of
